Let's go into this some more.
The Taliban are not broke. In fact, we've got a pretty good idea where their operating budget comes from.
1) Large donations from people who side with them ideologically. $500 million a year.
2) A 10% cut of the opium trade. Another $150 million a year, minimum.
3) Extortion. Anyone bringing goods through Taliban-controlled areas since 2018 had to pay a tax to the Taliban. Now, they have the whole country.
4) The mining industry. Much of it illegal, Afghanistan has a billion a year mining industry. In 2014, the Taliban took about $50 million of that. Now, they have the whole country.
Now, if the country is in poor economic shape, because a bunch of heavily-armed terrorists demanded they run the country despite not having the money or skills to do so, we're free to ask "why are they allowed to run the country?" and that goes to Trump, of course. Biden's just the one who didn't give them any extra money, which the Taliban surely knew they weren't getting. Or, you could make the argument the Taliban do have enough money to help their country, they're just choosing not to do it, in which case, once again, it's not Biden being the bad guy here.
People might not like the situation we've found ourselves in. I know I don't. But Biden's options were
1) Hand the Taliban terrorists billions of dollars, breaking the law to do so.
2) Sit on the money, having it do nothing.
3) Try to do some good with it, even if, yes, contractors will take some and the Taliban will likely steal some too.
I'm not going to fault Biden for taking the best way out of a bad situation he was handed by a mentally-deranged dictator, and the Taliban.
